[RFC PATCH 0/4] arm64:numa: Add numa support for arm64 platforms.

[Ganapatrao Kulkarni]

This is initial patch set to support numa on arm64 based platforms.
Tested these patches on cavium's multinode(2 node topology) simulator.
Tried all test-cases present in numactl-2.0.9 package.

In this patchset, defined dt bindings for numa mapping for memory
nodes. The cpu to node mapping is derived from the existing cpu-map
mapping as defined in topology binding.

thanks,
Ganapat
